<p>TO SUPPORT CELL SEARCH, MULTIPLE (E.G., TWO) SYNCHRONIZATION TRANSMISSIONS ARE SENT IN A FRAME WITH NON-UNIFORM SPACING.INFORMATION IS CONVEYED VIA THE NON-EQUAL DISTANCES BETWEEN CONSECUTIVE SYNCHRONIZATION TRANSMISSIONS. MULTIPLE LEVELS OF NONUNIFORM SPACING MAY BE USED TO CONVEY DIFFERENT TYPES OF INFORMATION. IN ONE DESIGN, THE MULTIPLE SYNCHRONIZATION TRANSMISSIONS ARE SENT IN DIFFERENT SUBFRAMES OF A FRAME, AND EACH SYNCHRONIZATION TRANSMISSION IS SENT IN ONE OF MULTIPLE SYMBOL PERIODS IN A RESPECTIVE SUBFRAME. THE SYNCHRONIZATION TRANSMISSIONS MAY BE SENT IN NON-EVENLY SPACED SUBFRAMES TO CONVEY FRAME BOUNDARY. ONE SYNCHRONIZATION TRANSMISSION MAY BE SENT IN ONE OF MULTIPLE POSSIBLE SYMBOL PERIODS DEPENDING ON THE INFORMATION, E.G., A PARTICULAR GROUP OF CELL IDS, BEING CONVEYED. THE DISTANCES BETWEEN SYNCHRONIZATION TRANSMISSIONS MAY ALSO BE USED TO CONVEY CYCLIC PREFIX LENGTH.A SECONDARY SYNCHRONIZATION TRANSMISSION CARRYING A CELL ID MAY BE SENT AT A PREDETERMINED OFFSET FROM ONE OF THE MULTIPLE SYNCHRONIZATION TRANSMISSIONS.</p> |
